However, Devon's Mother and Father looked different than Devon remembered them

Maria and Ducard wore evil clothing

Their skin was pale and their eyes glowed red

Red markings appeared all over their bodies

This meant only one thing: Devon would have to fight his own Mother and Father

"Mom? Dad?" Devon says baffled

"That's your Mommy and Daddy?" Bonehead asks

"Yes. But they were never like this." Devon says

"CORRECT. THIS IS NOT YOUR REAL MOTHER AND FATHER, DEVON. THESE ARE MERELY EVIL CLONES OF YOUR MOTHER AND FATHER. THEY ARE HERE TO FIGHT YOU AND YOUR FRIENDS. UNLIKE HOW FATE HAD THEM SLAUGHTERED BY MY HAND, I DECIDED TO HAVE YOUR MOTHER AND FATHER BE SLAYED BY YOUR HANDS. NOW YOU MUST FIGHT YOUR MOTHER AND FATHER!" Lord Thanatos says

"You should have stood up to Lord Thanatos, son. Like a man." Dark Ducard says

"Instead, you sat there and let us die." Dark Maria says

"How can we call you our son if you couldn't stand by our side against Lord Thanatos." Dark Ducard says

"I was only but a child back then!" Devon says

"Give in to the darkness, Devon. It will make your death so much easier." Dark Ducard says

"WELL DONE, DEVON. YOU HAVE SUCCEEDED IN BESTING YOUR MOTHER AND FATHER IN COMBAT. BUT NOW, IT IS TIME. TIME FOR YOU AND YOUR FRIENDS TO FACE ME IN BATTLE. THE ULTIMATE BATTLE IS AT HAND. NOW ONLY ONE OF US SHALL LEAVE HERE ALIVE." Lord Thanatos says in a deep, dark, demonic voice

"This ends now, Lord Thanatos." Devon says

"INDEED IT WILL." Lord Thanatos says

The chamber began to fade away

The group soon found themselves standing admist the dark clouds on top of a large spire

"In spite of all you have done in the past, I thank you for aiding us in our battle against Lord Thanatos. So what will you do now?" Devons says

"I'm not sure. The Tyranno Base was destroyed by Lord Thanatos. I guess we might as well head back to Reptilon." Genghis Rex says

"Wait. You might not have to go to Reptilon. You could join the Dinosaucers and help us protect this planet and Reptilon." Allo says

"We know that there is...some good inside of you." Devon says

"I've had a change of heart and have seen the error of my ways. So I will join you, Dinosaucers." Terrible Dactyl says

"I'm in too. This way I could see Nessie." Plesio says

"I know i'd be going against my father's wishes, but since our fight with Lord Thanatos, i've had a change of heart and have seen the error of my ways. So, the Tyrannos will now join you Dinosaucers and undo all that we have wrought." Genghis Rex says

"Are you sure, bossasaur? After all we have done?" Ankylo says

"Yeah, bossasaur. After all that we have done to them, do you really think we would be accepted into their group?" Brachio says

"After fighting alongside them against Lord Thanatos, I believe we have earned their trust." Genghis Rex says

"Are you feeling alright, bossasaur?" Quackpot asks

"Yes?! Why do you ask?" Genghis Rex says

"Well, you're usually not like this. You're usually evil." Quackpot says

"Since our encounter with Lord Thanatos, I realized he was more evil than I was. So I have seen the error of my ways. That is why I am committing myself to good than evil." Genghis Rex says

Devon, Allo, Bronto Thunder, Dimetro, Tricero, Stego, Bonehead, Ichy, Teryx, Genghis Rex, Styraco, Brachio, Quackpot, Ankylo, Plesio, Terrible Dactyl, Ryan, Sara, Paul, and David face off against the Mighty, All-Powerful Lord Thanatos. The group manages to defeat him and save the planet from destruction. Having defeated Lord Thanatos, the group returns to Lava Dome to celebrate their victory and surprise! The Tyrannos are reformed and join the Dinosaucers. Devon fulfills his duty as a Keyblade Wielder and leaves the Dinosaucers and into the stars. Thus concludes the Kingdom Hearts/Dinosaucers Crossover.
